Yamaha Engine zincs

[ron t]

I have a Yamaha 350 2009 on my 275 Tournament . I have the 2 external zincs that sit in the water changed anually. Does anyone have experience regarding when to change the other many engine mounted internal zincs. Thanks, ron t

my guys said engine zincs are rarely changed. they are inspected if anything looks odd with the bracket zincs (eg abnormal wear). ron
